Nouvelle hyperbole

Bravo!

a = 1 (slider from -5 to 5, step 1)
b = 3 (slider from -5 to 5, step 1)
h = 1 (slider from -5 to 5, step 1)
k = 4 (slider from -5 to 5, step 1)
c: 1 = (x - h)^(2) / a^(2) - (y - k)^(2) / b^(2)
d: 1 = (x - Random[-4, 4])^(2) / Random[-4, 4]^(2) - (y - Random[-4, 4])^(2) / Random[-4, 4]^(2)
